When is it good news to hear that radiation levels are 100,000 times higher than normal? When you at first thought they were 10 million times higher. Officials at Japan's stricken nuclear power plant say readings of staggeringly high radiation levels in water leaking from a reactor were mistaken. From the AP:

The day began with company officials reporting that radiation in leaking water in the Unit 2 reactor was 10 million times above normal, a spike that forced employees to flee the unit. The day ended with officials saying the huge figure had been miscalculated and offering apologies.

"The number is not credible," said Tokyo Electric Power Co. spokesman Takashi Kurita. "We are very sorry."

A few hours later, TEPCO Vice President Sakae Muto said a new test had found radiation levels 100,000 times above normal - far better than the first results, though still very high.
